CHARLES KESSES, OF NEW YORK, N. Y.

MOVING-PIGTUBE CAMERA.

s ecification of Letters Patent.

Application filed October 28, 1914. Serial No. 869,118.

To all whom it may concern:

lie it known that I, CHARLES Krissns, a citizen of the United States, and a resident of New Yorzcity, in the county of New York and State of New York, have invented a. new and useful lVloving-Picture Camera, of which the following is a specification.

My invention relates to improvements in moving picture cameras.

It has long been common to pull and release film for each exposure, with hooks or other mechanism, but since there are 12 to 18 and more pictures per second necessary to produce good results, this quick movement puts a terrible strain on the film and mechanism; also a sensitive film. in such quick speed, passing between two steel plates, having pressure of springs, to prevent film from sliding by exposure, will produce if the camera is in operation for sometime, electrical markings on the pictures.

I overcome this in my invention, by photographing on independent, constantly runningfilm.

This camera. does away with expensive perforating of film and feeds the film by means of rollers.

This camera is provided with an independent lens movement and a separated moving exposing slide; parts being as light and small as possibl tie camera.

A mechanical movement, consisting of an eccentric wheel and regulator lifts and lowers a lens in a plane and this movement can be regulated and set to the quickness re quired.

Suitable means are provided to hold a film on all sides steady and smooth in the rear of the lens, the film.

I attain these objects by the mechanism illustrated -in the accompanying drawings in which,

Figure I is a perspective view of the camera.

Fig. II is a top view of the mechanism.

throughout the several views.

Fig. III: 1 a lens in a 2x2 inch,.aluminum lens board running on rails 2 up and down; a spring 3 is just strong enough to lift lens to top of rails, said spring is fastened to the lens board and top of the camera. A square frame 4 is mounted on the lens board; said frame has openings on the sides allowing the passing of the front driviiig shafts, I

Fig. IV: 6 is a regulator, center of said regulator has a square sliding part mounted solidly to the front driving shaft 5.

Fig. V: 7 is aneccentric wheel, which. is mounted on a base to said regulator, the screws 8 on said regulator will regulate to move said eccentric wheel one or the other way. If the of pictures are i} of an inch high, then the eccentric wheel has to be set with said regulator to lower and lift the lens each way of an inch, both movements combined have tobe of an inch, to have perfect harmony in lens and film movement, av rim 9 running in ball bearings around said eccentric whee; said rim is a trifle smaller than the frame 4 to allow movcment of said rim, in said frame.

Fig. I: A curtain shutter 10 works over two rollers in one direction; bottom. roller is operatively connected to front shaft 5; said shutter has corresponding openings "11, to allow exposing, when the lens moves downward; said-roller has pins to lift in corresponding holes on both sides of the curtain; said curtain is divided an even number of opened and closed parts; the curtain is 'made'from black rubberized linen. Diameter of the bottom roller has. to be enough to transport by each exposure, one open and one closed part of said our tain.

Fig. I: 12 is a movable exposing slide, consisting of a hard rubber board; said exposing slide is'provided on both sides with rails 13 and has a center opening 14 size of picture to be taken; it prints a white marpictures.

Fig I: is a pin mounted on frame 4; said pin runs in an opening v in the exposmg slide to lift and lower said slide for every exposure. I
